  • Healthcare
  • Telecom

Sustainability Spotlight

  • R513A refrigerant is totally compliant to F-Gas Regulation (EU) 2024/573 and has a Low Global Warming Potential (GWP) of 631 as per IPCC AR4
  • R513A is a non-flammable refrigerant, completely safe from fire injection and flame propagation risks, in case of leakage, with a lower toxicity compared to other refrigerants (class A1 as per ASHRAE 34 Standard)
  • Inverter scroll compressor technology improves annual efficiency by up to 35% compared to a fixed speed compressor.
  • New generation of heat rejection condensers equipped with EC fans reduce even further power consumption and noise emissions.

Benefits

Higher Overall Efficiency Vertiv™ Liebert® PDX-PAM allows a continuous modulation of performance, maximizing part load efficiency, significantly reducing running costs. Eco-friendly without compromises Liebert® PDX-PAM is the perfect solution for the transition to a low carbon data center using a completely safe low-GWP refrigerant solution. The absence of flammability risks simplifies installation and limits costs increase. Unique Flexibility Liebert PDX-PAM offers a wide range of airflow configurations and delivery options that combined with easy and quick installation make it an extremely versatile unit that can satisfy any modern critical data center infrastructure. Cooling Continuity Its design and safety control logics allow to maximize reliability and continuity of operations. Each unit cooperates with the others (teamwork operation), but is completely independent from cooling continuity perspective.

Features

Inverter-driven brushless motor compressors with modulation capability down to 20% of maximum capacity allowing an optimum EER at part load conditions. Less compressor on/off cycles reducing starting current and improving power factor Last generation with low noise design centrifugal EC fans with speed modulation down to 30% of maximum value. Electronic Expansion Valve allowing Precise control of the evaporator feeding granting an Increased evaporator efficiency thanks to an optimal superheat control. Staged coil design with a cutting-edge and innovative patent pending filter solution. The Extended filter surface allows for greater air flow, less air pressure drops and reduced fan consumption. The innovative filter design significantly improve ease of maintenance. Vertiv™ Liebert® iCOM™ Smart control is the heart of the direct expansion cooling system, managing not only Vertiv™ Liebert® PDX units, but also outdoor Vertiv™ Liebert® HPA OAC remote condensers.
